`SAFETY CEMENT RAILROAD-TIE.

Specification of Letters Patent.

Patented oct. 12, 1915.

Application led February 8, 1915. VSerial No. 6,869.

T 0 all whom it may concern Be it known that I, WILLIAM M. PERKINS, acitizen of the United States, residing ,at North Manchester, inthecounty of Wabash and State of Indiana, have invented certain new anduseful Improvements in Safety Cement Railroad-Ties; and I do herebydeclare the following to be a full, clear, andy load has been lifted.

Another object of this invention is to provide an arrangement which isflexible in its transverse direction but rigidly keyed againstlongitudinal strain.

Another object of this invention is to provide an arrangement which isfirmly keyed to its bed.

Another object of this invention is to provide a composite tie providedwith longitudinal reinforcing elements, said elements adapted to lockthe rail to the tie.`

Other objects and advantages of this invention will be hereinafter moreclearly set forth in the specification and pointed out in the claims.

Similar characters of reference refer to similar parts throughout thespecifications and claims, in which,

Figure 1 isa top plan view of this device in assembled formation. Fig.2, is a sectional elevation of the same, and, Fig. 3 is a sectionalelevation of a portion of the tie Ishowing a modified form of means forclamping the rail to the tie.

In the drawings, the tie is composed of like members 1 and 2 preferablyformed of concrete, each fof said members having a longitudinal recess 3in the top portion thereof and a longitudinal recess in the lowerportion thereof in which are mounted metallic bands or plates f1 and 5,said plates being integral their full length of the upper portion of thetie members and being seated in the groove 3 and extending beyond theinner ends 6 and 7 of the tie members and loopedback and seated in thelongitudinal recesses in the under portion of the tie members. Aplurality of vertically'positioned apertures 8 are .formed in each ofthe tie members through each of which is mounted a sultable sleeve 9,the metallic bands 4 and 5 having apertures adapted to register with-the apertures through the tie members.

Locking means l0 are mounted through these apertures, a portion of whichare adapted to clamp a rail 11 of ordinary construction and theresilient bed pla-te 12 thereof to thetie to prevent lateral movement ofsaid rails, said fastening means 10 having threaded ends 13 seating thelocking nuts 14: for this purpose. Between the looped ends of each ofthe bands 4 and 5 andthe ends 6 and 7 of eachl of the tie members aremounted metallic structures 15 and `16 as shown in Fig. 2, Saidstructures and bands LLand 5 being preferably curved on their lowerfaces so that the major portion of the tie will be directed on thecenters of 'each section. A vertically disposed aperture 17 is formed ineach of these metallic members through which is mounted a locking bolt10 held in position by the nut 14. A pair of oppositely disposed linkmembers 18 and 19 are placed upon the sides ofv these metallic membersand locked into posiing said link members in true parallel alinementwith one of said tie members, the other member being allowed to play. Itis to be further noted that the heads 22 of the bolts Y Asame tieconstructions are used as illustrated above, the members 1 and 2 havingthe bands 4: and 5 therearound, the raily 11 and the bed plate .12, butin this instance the resilient ,base plate 12 is wider than the baseflanges .of the rail 11, said base ianges and said base plate havingregistering apertures there.

through. Anchoring plates 23 and 24 are' oppos1tely disposed above thebase flanges of the rail, the ends of which abut against the web of saidrail, said plates extending to a neighboring locking bolt 10, saidanchoring plates 23 and 24 having suitable apertures therethrough toengage the locking bolts 10 which are mounted through the saidregistering apertures, so that when the nuts 14 are threaded home, saidanchoring plates 23 and 24 will securely bind the rai-l in position andprevent lateral displacement of the rail, the strain of saiddisplacement being taken up by the neighboring locking bolts 10.Suitable angular washers 25 are 4placed between the flanged ends of theanchoring plates 23 and 24 and the nut 14 to prevent distortion of thelocking bolts 10. By this arrangement when the load of passing cars isdelivered to the ties, each portion thereof will properly giveftherebyallowing of a r,e silient action of the rail l1, yet preventing lateraldisplacement of said rails,\said ties returning to their normal positionafter the load is released from off said ties, and likewise by means ofthe bands 4 and 5 and the locking bolts 10, the strain of thisdisplacement is distributed to all points of said tie thereby insuring astrong and durable arrangement.

Having now described my invention what I claim as new and desire tosecure by Letters Patent, is:

1. A composite railroad tie, comprising oppositely disposed members,metallic loop members reinforcing said oppositely disposed members, ametallic structure mounted in the looped portion of each of saidmetallic means, and pivoted connecting means, connecting said oppositelydisposed members, and pivoted through said metallic structures to allowof resilient play of said members.

2. A composite railroad tie composed ofQ oppositely disposed concretemembers having transverse vertically disposed apertures therein, sleevesmounted in said apertures, a looped metallic band above and below eachof said concrete members, said bands having apertures registering withthe apertures in said concrete members, reinforcing fastening meansvpassed through said sleeves and locking. said metallic bands and linkingmeans pivoted in the loop portion of said bands to allow of resilientplay of each of said concrete members.

3. A composite tie comprising oppositely disposed concrete membershaving longitudinal recesses in the top and bottom portions, a metalliclooped band, seated in' said recesses the loop portions thereofextending beyond the inner ends of said concrete members, metallicstructures mounted in said looped portions, pivoted connecting meansmounted throughr said metallic structures and connecting said concretemembers, transverse locking 'reinforcing elements mounted through saidconcrete members and said metallic bands to reinforce and lock the samein position, a rail plate, a rail mounted upon said rail plate, andmeans locking said rail to a portion of said transverse locking means.4. A composite tie comprising oppositely disposed members, loopreinforcing members, metallic members in said loop members, pivotedlinking means mounted on said metallic members and abutting said loopportions, a rail plate mounted upon each of said oppositely disposedmembers, a rail mounted upon saidrail plates, and bolt means passingthrough said loop members and said oppositely disposed members, aportion of which operate to fasten said rails, the lower ends of saidreinforcing means operating to anchor said tie to its bed to preventdisplace ment therefrom.

ln testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
